1.1.1 Incident Category
1.1.2 Site Description
The Site is bordered with temporary fencing to restrict access and prevent exposures to the impacted area. The soils containing the high metal concentrations are in white or gray clay-like material with colored streaks. The lenses are observed in near surface soils to a maximum depth of about 3 feet and cover an area of approximately 160 ft by 55 ft. The clay-like material reportedly originated from industrial waste lagoons that were operated prior to 1974 by the former Bettenger Company on the abutting, upgradient property at 51-53 Sumner Street prior to 1974. The lagoons were discontinued and similar metals-contaminated, clay-like material was excavated from the lagoons in 1987. The BMC currently owns the upgradient property.
1.1.2.1 Location
The Site, located on town municipal property to the rear of 51-53 Sumner Street in Milford, Worcester County, Massachusetts, contains part of the Milford Upper Charles Trail (Bike Path) and is adjacent to Cedar Swamp Pond. It is bordered on the north and south by other portions of the bike path, to the east Cedar Swamp Pond and its associated wetlands, and to the west by the Benjamin Moore Co. (BMC) facility. The geographic coordinates, as measured from the approximate center of the property, are 42º 09′ 08″ north latitude and 71º 31′ 02″ west longitude.
1.1.2.2 Description of Threat
High concentrations of lead and other heavy metals have been found in the soil on the Site. Rain and runoff can assist in the migration of these contaminants into the wetlands and into Cedar Swamp Pond.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
In January 2011, the Massachusetts Department of Environmental Protection (MassDEP) requested that the USEPA Region 1 Emergency Planning and Response Branch consider the Site for an RA due to concerns that there could be a significant environmental and public health threat because of potentially high concentrations of heavy metals in the soils. The OSC conducted a Site Assessment which evaluated November 2006 analytical data from Milford and MassDEP May 2011 analytical data to assess the extent of contamination. Both data sets noted in the surface and subsurface soil high levels of antimony, barium, cadmium, chromium, lead, lithium, nickel and zinc. All the soil samples in 2006 and 2011 showed these heavy metals concentrations above the MA action levels.

2.1.1 Narrative
A site walk was conducted on December 2, 2011. EPA, ERRS, and START personnel walked the Site and met with the Milford Town Engineer. Manning and equipment needs were decided on and coordinated. ERRS personnel mobilized to the Site on 12/5/2011.
2.1.2 Response Actions to Date
During the week of 12/5/2011, The Site was secured using the temporary fencing already on the property, erosion control measures (hay bales and silt fence) were deployed, and the hazardous soil pile containment area was constructed. In addition, the request for bids went out to potential T&D subcontractors on 12/8/2011..
During the weeks of 12/12/2011 and 12/19/2011, Soil excavation started and continued through 12/22/2011. Approxiamately 30-50 tons a day has been removed and staged in the containment area. In addition, the bidwalk for the T&D subcontractors was held on 12/13/2011.
